Dissipative Solutions to Compressible Navier–Stokes Equations with General Inflow–Outflow Data: Existence, Stability and Weak Strong Uniqueness

نویسندگان

چکیده

So far existence of dissipative weak solutions for the compressible Navier–Stokes equations (i.e. satisfying relative energy inequality) is known only in case boundary conditions with non zero inflow/outflow (i.e., particular, when normal component velocity on flow domain equal to zero). Most physical applications (as flows wind tunnels, pipes, reactors jet engines) requires consider non-zero inflow–outflow condtions. We prove barotropic regime (adiabatic coefficient $$\gamma >3/2$$ , three dimensions, >1$$ two dimensions) large prescribed at and density inflow a bounded piecewise regular Lipschitz domain, without any restriction neither shape boundaries nor domain. It well that inequality has many applications, e.g., investigation incompressible or inviscid limits, dimension reduction flows, error estimates numerical schemes. In this paper we deal one its basic namely weak–strong uniqueness principle.

Existence and Uniqueness of Global Strong Solutions for One-Dimensional Compressible Navier-Stokes Equations

We consider the Navier-Stokes equations for compressible viscous fluids in one dimension. It is a well known fact that if the initial data are smooth and the initial density is bounded by below by a positive constant, then a strong solution exists for a small time. In this paper, we show that under the same hypothesis, the density remains bounded by below by a positive constant uniformly in tim...
